When President Trump took office on January 20, his supporters hoped he’d keep his campaign promises to get tough with China on trade and push it to deal more forcefully with North Korea; renegotiate or pull out of NAFTA; withdraw from the Trans-Pacific Partnership trade deal; and dismantle the Iran nuclear deal. Meanwhile, critics in the US and around the world hoped that those same campaign promises would prove to be hollow threats. Trump’s first year in office has given both sides reason to cheer — and reasons to worry about what may happen in the year to come.
